I bought a Samsung Q90T a few weeks ago, and I'm currently playing on the Series X. While playing Assassins Creed Valhalla- the screen brightens when I press the Xbox button- on game mode and off of game mode. It washes out the pictures and make everything look foggy. When I reset the TV by holding down the power button, everything returns back to a normal a picture setting. Is there a fix for this or did I spend 1000's of dollars for no reason? It's not a local dimming setting, or any kind of options I have enabled.
